Custom standartised JSON response for Zend Framework - php

Question

I want standartise all JSON responses ( something like Standardised JSON response from views ).
Here is JSON response example
{
"status" : "failure",
"errors" : {
"name" : [ "Error text 1", "Error text 2" ],
"email" : [ "Email error text" ]
}
}
And here is class implementing my standartised JSON response
class JsonResponse
{
protected $_errors = array();
public function addError($key, $value) {
$this->_errors[$key][] = $value;
return $this;
}
public function setFormErrors(Zend_Form_Abstract $form) {
$this->_errors = $form->getErrors();
return $this;
}
public function __toArray() {
if (!empty($this->errors)) {
return array(
'status' => 'fail',
'errors' => $errors,
);
}
return array(
'status' => 'success',
);
}
public function __toString() {
return json_encode($this->__toArray());
}
}
Everything is great, but using this class is real pain in the ass.
class App_Controller extends Zend_Action_Controller
{
public function submitAction()
{
$form = new App_Form();
$form->isValid($this->getRequest()->getPost());
//disabling displaying layout
$this->_helper->layout()->disableLayout();
$this->_helper->viewRenderer->setNoRender(true);
$response = new JsonResponse();
$response->setFormErrors($form);
echo $response;
}
}
I'm real noob in Zend Framework.
What is the best way to wrap JsonResponse to?
helper
extend Zend_Controller_Response_Abstract
new context switch
implement in Form
What is the best approach?
Creating a custom JSON response object with Zend Action Helper ContextSwitch - nice way of doing it, but still requires too much code, imho.

Answer 1

IMO you should use a context switch (JSON or your own) and use your preferred way to format your response data structure.
It seems like you are implementing the ajax form validation aren't you ? Maybe you should have a look on this : Zend form ajax validation on submit (and ask google about processAjax())
